BRUSH.

T 0 all 207mmz't may cmwem:

Be it known that I, lVILL-IAM G. Ronrxn, a citizen of the .United States, residing at Hudson, in the county of St. Croix and State of Wisconsin, have invented certain new and useful Improvements in Brushes, of which the following is a specification.

' This invention relates to brushes of special construction and more particularly to the type, having bristles arranged to contactingly encompass an annuler section of pipe or other elongated cylindrical body, for the purpose of scouring the same, an object ot the invention being, the provision of a cheap, strong, sanitary and efficient brush for use in olcaning the rotary coils of sterilizing tanks in creameries. Brushes of various sorts are being used fort-bis purpose, including the ordinary scrub brush, but, all are more or less unsatisfactor in .that their use is slow, tedious and uueertain, parts of the surface in many instances accidentally' remaining untouched. As these coils are very hot, incrustation takes place, leaving a tenacious crust on the surface thereof, requiring a brush of stiffbristles to dislodge it.

As these cols are mounted on a central rotating shaft, and have, at intervals, radial supporting struts extendifig from the latter, and are coiled to a relatively small pitch, ordinary scrub brushes are too bulky for economic use in the Qrestricted space between the individual coils, While a flexible brush, formed of a plurality of connected individual fiat brushes, cannot be successfully used, beeause the bristles do not radiate to the center of the pipe, nor can the latter be eflectively contactingly surrounded by the same, as the struts Will block its continuons travel from one end of the moving coil to the other.

An object of my invention, is to provide a brush with relatively stifi' bristles, Which may be held by hand against the revolving coil to bring the latter in frietional surrounding relation with the coiled pipe, and which is constructed so as to be swingingly separable to permit the struts to pass between the members constituting the brush, without removing the latter from operative position, as the operator propels the brush along the helix described by the coil.

To this end, the invention consists in the construction, combination and arrangement of parts hereinaffer described and claimed.

V .ntl1e drawings forming fication:

Figure 1 is a perspective view of a brush cznbodying my invention.

Figure 2 is a side view drawn to a reduced scale, showing the bristle side of the brush members.

Figure 3 is a side view 01" the invention show1ng it in its normal open position, and the manner cf applying it to the pipe.

Figure l is a ragmentary perspective v iew of a coil, shovving the device in opera tive position.

Figure is a and Figure 6 is a sectional view of a round strut, sliowing it in engagement with the jaw formed by the brush members.

The invention as shown, comprises two segmental brush members, A of similar iorm, each describing approximately a semicircle, said brush members being hinged together, preferably by a Ushaped stziple B, the legs ofthe latter being parallel and constituting pintles rotatably projected, one tl1roHgh each of the brush members, at a position adjacent the extremity thereof, whereb the brush members are rendered swingable away from each other, preferably to a limited degree, and toward each other into contacting relation at their opposite free ends 2. The rounded ends 3, of the brush members, are non-concentric relative to the pintles l, so that when the members are svvung outwardly said ends Will contact with each other to restrict said outward movement. A spring 4 straddling the hinge connection, is formed vvith outwardly divergings arms 5, suitably secured, as by the sharpened peg end 6 in the respective brush members, whereby the latter are held normally in spread position as indicated in Figure 3. The ends 2 are preferably ont radial relative to-the central bore or circular open ended chamber 7, formed by the two brush members, vvhen said ends are closely adjacent each other. Extending from the arcu ate walls of the chamber 7, and suitably distributed thereover and in radial relation thereto, are the bristle tufts 8, the latter being secured in the usual way (mot shown) in the semi-eiroular shaped shells 9 forming the bodies of the brush members. T he shells 9.

part of: this speciplan view of the bingo staple,

are of parallel width, each being formed with a handle 10, whereby to facllitate the the heatingcoil F.

manipulation et the brush when in use. It- Wlll be noted, that the handle is integral and disposed longitudinally of the bore 7, so that in manufacturing the shells great advantage is aflorded, inasmnch as the shells may be easily and quickly ont out of a*plank on a band SaW. Referring now to Figure 4, (wherein the parts are semi-diagrammatically indicated) C designates a tank, and D a horizontal shaft rotatably supported thereon. Extending radially from the shaft are the strut supports E, whereon is supported A-A designates the brush members, being pressed in surrounding relation against the circumferential surface of the coiled pipe, the hands of the operator being shown in dotted limes. As the coil revolves and threads its way through the brush, the opeiator walks along side ac coidingly, holding the brush members firmly, (against the stress of the spring 4) a'round the pipe. As the struts are encountered, the operator permits the brush members t0 slightly separate, under the action of the spring, t0 permit the strut to pass therebetween, the ends 2 of the shells 9 being eut away at an angle at 11 to form together a V-shaped j aW 12, wherebyto facilitate the entrance of the struts.

The legs 1 of the. hinge staple have suitable notches 13, whereby they may be bent at right angles to hold the hinge against withdrawal.

The hinged brush members may be said to form a split ring, each member constituting a segmental brush with convex back.

I claim:

1. A brush comprising a plurality of brush members each ofarcuace form and having bristles xtending inwardly from their concave faces, each brush ncember be- 1ng formed with an opemng extending m an axial direction adjacent one edge, a subpintle memher coacting t0 limit the open- 7 ing movement of the brush members, and

means for urging the brush members closed.

2. A brush comprising arcuate brush members hingedly connected together, each member having a peripheral rib extending lengthwise thereof and intermediate its side edges to provide manipulating handles, and a spring extending across the hinge connection between the brush members and arranged outwardly theieof, the termirials of the spring being anchored to the respective members.

3. A brush -comprising segmental brush members, means arranged within the body limes of the brush members and inwardly from themeeting edges thereof for hingedly connecting said brush members, a coil spring disposed outwardly of the meeting edges and having its terminals extending in 7 opposite directions and'beyond saidmeans and 7 anchored toi the respective brush members, each brush member being formed adjacent the point of securement ofthe spring terminal with a raised hand grip extending lengthwise of the member.

In testimony Whereof I aflix my signature inpresence of a witness. r
